Homework Equations
Ex = (Kλ/R)*∫_{3/2π}^{π/2}(cosθ)dθ
The Attempt at a Solution
Ey cancels because there is an equal amount of force in both y directions. For the electric field on the x axis, the above equation can be used.
Given that λ=Q/L
λ=(85x10^9 C)/(0.1 m)
=8.5x10^7
R = L/θ
=(0.1 m)/(3/2π  π/2)
=0.03183
E = ((8.85x10^9)(8.5x10^7)/0.03183)*pi
= 7.424640507894822×10^13
This is not correct. Please help! Thanks in advance.
